3 Description
The TPL5100 is a long-term timer IC optimized for
low-power applications. The TPL5100 can replace a microcontroller's internal timer, allowing the
microcontroller to stay completely off instead of
running a timer, providing a total power consumption
reduction of 60 to 80%.The TPL5100 is designed for
use in power cycled applications and provides selectable timing from 16 seconds to 1024 seconds.
The TPL5100 can also monitor a battery
management IC via a power-good digital input and
power on the microcontroller only when a good
supply voltage is present. The device is packaged in
a 10-pin VSSOP package.
